FIELD OF THE INVENTION

The present invention relates to a raised access floor unit, particularly, to a raised access floor unit with simple structure and stability suitable for stone or tiles to be laid thereon.

DESCRIPTION OF THE PRIOR ART

For those working places widely using computers, distribution and laying-out of networks and other kind of lines are very important and necessary. Because each computer can only be connected or electrically connected with other computers through a network, intertwining of lines becomes more and more complicated when amount of equipment gets larger and larger. If in an office lines are exposed outside, they not only look ugly, but also affect walking of workers. A floor for networks because of being able to be elevated for assembling, it leaves at its bottom a space for threading and distribution of lines. Thereby for informationalization of a modem office, it has been a main trend to flexibly decide the amount of floors laid out in pursuance of the size of the space in an office.

Presently it is common in the art to use floor coverings such as carpets, stone or tiles on the raised access floor to make it pleasing to the eye. The structure of the conventional raised access floor, as shown in FIG. 6, are mainly cement B clad with alloy steel A having stoving varnish on the surface, so as to make the raised access floor delicate and lay carpets on the raised access floor in the future. When stone or tiles are laid on the raised access floor, an adhesive is necessary to be applied on the alloy steel to stick the stone or tiles on the alloy steel. Although the abovementioned massive structure of the conventional raised access floor made of cement and alloy steel can ensure the structure not to be deformed or weaken after the laying of stone or tiles, however, in practice, it is not easy to stick stone to alloy steel, and the stoving varnish on the surface of the alloy steel can be prone to peeling off during the laying process, causing that surface of the alloy steel to be damaged. Therefore, when replacing the stone or tiles in the future, the damaged raised access floors have to be replaced together with the stone or tiles, which is uneconomical and inconvenient to users.

In addition, while the stone is laid on the raised access floor, the raised access floor cannot be easily removed as the way using a cupule for a wooden floor due to the stone, thereby rendering construction inconvenient during the laying process.

In order to overcome the foregoing shortcomings and problems, after hard research and development, a raised access floor unit that substantially departs from the conventional concepts and designs of the prior art is provided by the present invention.

SUMMARY OF THE INVENTION

The primary object of the present invention is to provide a raised access floor unit with simple structure, stability, and facilitation for combining stone or tiles.

Another object of the present invention is to provide a raised access floor unit having stone thereon, wherein the raised access floor unit is convenient to be removed by operators during the laying process.

In order to achieve the aforementioned object, the raised access floor unit according to the present invention comprises a frame member and a block member, the frame member has a receiving space for raw materials of the block member to be poured and harden inside the receiving space, characterized in that the bottom of the frame member is disposed with a plurality of T-shaped plate members, wherein the plurality of T-shaped plate members are formed directly from the bottom of the frame member so as to dispose the plurality of T-shaped plate members into the block member while the raw materials of the block member are poured to the frame member, thereby allowing the block member to be incorporated into the frame member securely.

In practice, the frame member is made of metal.

In practice, the frame member is disposed with folded flanks around the rim to form the receiving space, and the height of the plurality of T-shaped plate members are lower than the height of the folded flanks.
